Background: Barriers to palliative care still exist in long-term care settings for older people, which can mean that people with advanced dementia may not receive of adequate palliative care in the last days of their life; instead, they may be exposed to aggressive and/or inappropriate treatments. The aim of this multicentre study was to assess the clinical interventions and care at end of life in a cohort of nursing home (NH) residents with advanced dementia in a large Italian region.Methods: This retrospective study included a convenience sample of 29 NHs in the Lombardy Region. Data were collected from the clinical records of 482 residents with advanced dementia, who had resided in the NH for at least 6 months before death, mainly focusing on the 7 days before death.Results: Most residents (97.1%) died in the NH. In the 7 days before death, 20% were fed and hydrated by mouth, and 13.4% were tube fed. A median of five, often inappropriate, drugs were prescribed. Fifty-seven percent of residents had an acknowledgement of worsening condition recorded in their clinical records, a median of 4 days before death.Conclusions: Full implementation of palliative care was not achieved in our study, possibly due to insufficient acknowledgement of the appropriateness of some drugs and interventions, and health professionals’ lack of implementation of palliative interventions. Future studies should focus on how to improve care for NH residents.

The frailty sex paradox has recently gained attention. At all ages, females are more likely to be frail and show a more severe phenotype but have a higher survival rate compared to males. The main aim was to test sex-specific differences in frailty syndrome using a multimodal evaluation from clinical and imaging data to deepen the understanding of different underlying mechanisms involved in the two sexes, and thus understand the association with different risk factors. Ninety-six community-dwelling older adults were characterized by clinical underpinnings (Fried’s frailty indicators: comorbidity, depression, global cognitive level, physical activity, autonomy), and neural integrity (T1-weighted brain 3T MRI). The frailty × sex interaction in clinical and neural profiles was tested. Additionally, frailty risk factors were identified in the two sexes separately. Results showed that fragility was associated with an increment of depressive symptomatology in females, while a decrement in physical activity was observed already in the pre-frail stage in males. Finally, different risk factors were observed in the two groups: significant frailty predictors were neural integrity and physical activity in males, and age and depression in females. These data support the starting hypothesis of at least partially different mechanisms involved in the frailty phenotype between men and women.

We describe a patient (CG) suffering from early onset dementia who presented with corticobasal syndrome (CBS). The aims of the study were as follows: (i) a detailed description of the cognitive phenotype; (ii) a comprehensive, longitudinal evaluation of apraxia; (iii) an appraisal of the impact of apraxia and other cognitive impairments on patient functional status; and (iv) an indirect mapping of degeneration spreading. A three-year longitudinal, observational follow-up study of cognitive and functional status was performed. Four main results emerged. First, an unusual CBS phenotype appeared that was characterized by symmetrical presentation, asymmetrical course, and prominent posterior (bi-parietal) cognitive and motor cortical manifestations. Second, some findings of limb apraxia in CBS were replicated and substantiated; moreover, some novel findings of other cognitive impairments emerged. Third, an early, significant functional decline, probably related to apraxia and to visuospatial attention impairments, became apparent. Fourth, CG’s clinical picture was compatible with an underlying dysfunction of the large-scale, dorsal sensory-motor association network, as already suggested in previous CBS cases. This case report confirms the heterogeneity of CBS and suggests the emergence of a possible less common variant, i.e. the posterior CBS (P-CBS).

Background: Dementia has an impact on the physical activities performed daily in a social context. Sleeping and resting, in general, are also affected by dementia. Monitoring techniques based on miniaturized wearable sensors and on sensorized environments allow for actigraphic recordings and location tracking. The availability of contemporaneous physical activities profile led to quantify, in the social actigraphy approach, the level of correlation between individuals living in the same environment. Objective: This study has two main objectives: (1) to define a methodology for actigraphic recordings, based on wearable accelerometers, and on location tracking, based on Bluetooth wearable technology, and to apply it in a well-defined social context, a long-term care residential unit for people with dementia; and (2) to quantify test-retest reliability of the indices obtained by the monitoring methodology. Methods: Persons with dementia living in the long-term care unit have been equipped with miniaturized wearable sensors, an accelerometer at their dominant wrist, and a Bluetooth beacon at their ankle for 7 days. The raw recordings allowed for computing indices related to physical activity intensities, to the occurrence of walking bouts, to the efficiency of sleep and waking phases, to social interactions between individuals, and to locations preferably occupied. The 7-day session was repeated at short (3 weeks) and long (3 months) terms in order to quantify the test-retest reliability of the indices. Results: Twenty-five persons with dementia were enrolled, 4 of them dropped out, and valid data were obtained, in the different sessions, from 19 to 21 individuals of the recruited group. Control data from 10 age-matched healthy participants were derived from published datasets. As a group, compared with age-matched healthy participants, persons with dementia showed a comparable duration of phases of no activity and of light activity (energy cost lower than 3 metabolic equivalents of tasks [METs]), a relevantly lower duration (−84.3%) of phases of moderate activity (energy cost ranging from 3 to 6 METs), and substantial absence (−100%) of phases of vigorous activity (larger than 6 METs); moreover, daytime and nighttime were characterized by comparable wake and sleep, respectively, efficiency; finally, as to the social interactions, persons with dementia showed a lower correlation of their motor activity profiles (−53.1%). The test-retest reliability was excellent for physical activity indices (intraclass correlation coefficients ranging from 0.76 to 0.98), good for social indices (0.65‐0.67), excellent for sleep or wake efficiency (0.74‐0.89), and fair for location tracking indices (0.37‐0.78). Conclusions: The considered methodology, particularly concerning accelerometry, proved to be feasible, informative, and with a good to excellent test-retest reliability. Interestingly, the methodology clearly identified behaviors, such as wandering, in a minority of individuals inside this study’s group of persons with dementia, thus supporting a possible clinical use of the methodology.

Technologies for frail elderly individuals facilitate the integration of care services, support the post-discharge period, and enhance independence and quality of life while reducing isolation. However, the lack of methodological rigor in studies on technologies for diagnosing and treating geriatric syndromes limits applied research. This study aimed to develop and validate a checklist considering technical readiness, clinical needs, and context to support the use of technologies primary in clinical practice and also in research settings. To this aim, a Delphi procedure was conducted in four rounds, followed by a pilot test assessing the checklist’s practical effectiveness. Twenty-nine items were defined and discussed. Among them, no item was deleted, while a total of eight items were reformulated. At the end of the assessment steps, 73% of items showed a high median relevance rating. The pilot test showed the difficulty in finding relevant information to complete the checklist as the only critical issue. This tool represents the first validated checklist in the field of technology-based healthcare for elderly individuals and supports the application of technologies in the diagnosis and treatment of geriatric syndromes by clinicians and researchers.
